Asymptotic BEP and SEP of MRC in Correlated Ricean Fading and Non-Gaussian Noise
— In this paper, we study the asymptotic behavior of the bit–error probability (BEP) and symbol–error probability (SEP) of coherent maximum–ratio combining (MRC) in correlated Ricean fading and non–Gaussian noise, which in our definition also includes interference. We derive simple and easy– to–evaluate asymptotic BEP and SEP expressions which show that at high signal–to–noise ratios (SNRs) the performance of MRC depends on certain moments of the noise and interference impairing the transmission. We provide closed–form expressions for these moments for practically important types of noise such as Gaussian mixture noise, correlated co–channel interference, and correlated Gaussian interference. Interestingly, our results show that not only fading correlation but also noise correlation has an adverse effect on the asymptotic BEP and SEP.
